Explanation:
Since the compass uses a magnetic field, if anything else magnetic is near it, the compass will start acting up. Making it unreliable so keep magnets away!
Answer:
No car will slide
Explanation:
Neither car will slide because proper bank does not required frictional forces. To prevent the car from traction through curve, a component of normal forces provides necessary centripetal forces. which prevent them to slide.
No car will slide since both car are going with the proper speed for given banking angle
Answer:
Explanation:
Period of oscillation ∝ √ m
So period of oscillation is proportional to square root of mass
So when mass increases , period too will be increased . But the total energy will remain the same as per conservation of energy.
Hence option ( D) is the correct answer.
Answer:
Mechanical, chemical and heat ?
